Stefani was the unofficial queen of sleeveless, decorated crop tops in the '90s, when the popularity of her band No Doubt was at its peak, sporting them onstage and in many of the group's music videos.

InStyle's December 2015 issue is out on Nov. 13. The magazine interviewed her at the $13 million Beverly Hills home she shares with Gavin Rossdale, her husband of 13 years, father of their three sons and soon-to-be-ex.

Stefani talked to InStyle about balancing work with her personal life as a married mom in the years leading up to her and Rossdale's divorce.

"Every day I would take the kids to school, drive to Santa Monica, work the [new No Doubt] album, and then I'd think, 'Oh my God, if I don't leave by 2:30, I'm not gonna get home in time for dinner. And Gavin being on tour...I'm not gonna say there weren't some incredible moments making that album. But it was a lot of knocking my head against the wall. A lot of struggle."

"I got so much out of that first season that I didn't expect, creatively, from being around so much music," Stefani told InStyle, adding, "There were hard times before the baby, personally, that were just not good. And then having Apollo, and being on the show, and being refreshed— it was just like, Whoa!"

"Filming the show...was so amazing," she said. "I cried every day I was there. It was so intense. But I'm in a really positive place now."
